ANTICHOXE ROLL AGITATOR. j

Application filed April 19,1927.l Serial No. 185,012.

The presen'tinif'ention relates to an agita tor and las for its object to provide means Ywhich will assist the roll m acotton gin m turning so as to give the yroll an even turn from end to end. As is well known the rollA without an Vagitator gives much trouble, sometimes stopping in the center or at either end.

Another important object of the invention is to provide a structure ofl this nature which is e'cient and reliable in its operation for imparting uniform movement to the roll so as to prevent the gin saws from cutting the cotton fiber which is so frequently the cause of the ruination of the staple of the cotton.

A still further important object of the in" vention lies in the provision of a structure of this nature which is simple in its construction, inexpensive to manufacture, easy to install, and otherwise well adapted to the purpose for which it is designed.

lVith the above and numerous other objects in view as will appear as the descriptien proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: Figure 1 is a fragmentary front elevation of a roll box witha portion ofthe front taken away to show the interior mechanism the novel features of this invention,

Figure 2 therethrough,

Figure 3 is an end elevation thereof, Figure l is an enlarged ldetail section show-v 0' the spider, the head, and the shaft asis a transverse 'vertical section ing.

sociated together,

Figure 5 is a perspective View of the shaft,

and

' Figure 6 is a sectional view through the shaft showing one ofthe crossrods in ele vation, Y -K Referring to the drawing in detail, it will be seen that the numeralv 5 denotes the roll bof; Vhaving journalledtherein'a shaft 6 on which is disposed a plurality of gin saws 7 of conventional or any preferred construction. These saws 7, of course, are disposed in spaced relation as is clearly indicated in Figure 1. rlhe sides of the roll box 5 above the saws 7 are formed with openings 8 and 55 spiders 9 are formed on the outside of thel sides of the'box 5 to cross the openings 8.y A shaft 10 is journalled inthe spiders 9 andv has collars lllixed thereto, one adjacent each spider 9. This shaftv l10 is formed with 6c a` plurality of spaced openings 12 alternately arranged at right angles to each other. These openings l2 receive rods 13 the center portions of which are anchored in theopen- 4ings 12 'by means of set screws 14. These 6a rods 13 are suiliciently long to move between the `upper portions of the gin sawsl 7 when the shaft 10 is rotated as is clearly indicated in Fig. 2. The shaft 10 rotates in an op posite direction from the shaft 6 as is Ain-y 7" dicated clearly by the arrows in Figure 2. A pair of heads 15 are disposed on the shaft v1G for closing the openings 8. The shaft f l() is rotated at one-fifth thespeed vof the shaft 6 in any suitable manner such as 7 through pulleys lGland 17 operatively connected togther by a belt 18. The pulley 16' is mounted on the shaft 10 at an end thereof exteriorly of theroll box 5 while the pulley 17 is mounted on a lshaft 19 brackets 20.

This attachment efficiently prevents the roll from stopping and'keeps it uniform from one end to the other. The attachment also lessens the strain on the saws and prevents the saws from `cutting the cotton. As is wollr known when cotton .is being ginned, andthe rroll becomes too tight and cholres and `does lnot turn. the ginA saws passingthrough the cholre roll cuts the cotton fiber and ruins the staple of the cotton. This attachment effectively prevents this because it 1 assists the roll in turning and thereby prevents the same from becoming choked.

It -is thought that the construction, opera-v tion, utility, and advantages of this inven-v tion will nowbe quite apparent to'those v skilled in this art without a more detailed description thereof. 1 The Vpresent embodiment of the inventionhas been disclosed in V j ournalled in so description. It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing `from Ithe spirit or scope of the "invention as hereinafter claimed or sacrificing any of its advantage's.

Having thus described our invention, what we claim as new is:

l. In a cotton gin, a roll box, a shaft jonrnalled in the roll box, vgin saws on the shaft, the sides of said roll box being yprovided with openinv's and formed with exterior spiders eros., ng the openings, a second shaft 4jon'rnalled in fthe spiders 4to cx- 'tend in Vparailelisin. with the first shaft, ieads on the second shaft to `close the openings, v'said 'second shaft provided with na plnral'iity of transverse openings arranged in alternate rio'ht angular relation, rods extending vthrongh the openings, .means 'for fixing the vcizenters ofthe rods in the opening-s, said rods being' sntlicien'tly long to swing between the gin saws.

2. In a cotton gin', a roll box, a shaftjonrnalled in the roll box, gin saws on the shaft, thesides of said roll box being provided with openings and lfornned with exterior spiders crossingthe openings, a second shaft, jonrnalled in the spiders to extend in Vparal'lelisni with the first shait, headson the second shaft to close the openings, said Vsecond shaft provided with a plurality ot transverse openings arranged in alternate right angular relation, rods extending throng'h the openings, nieans for fixing the centers of the rods in the openings, said rods being su'tliciently long to swing' between the gin saws, collars on the second shaft, one adjacent each spider' for prevent-V ingl end play ot said second shaft, and n'ieans' for rotating. the shafts in opposite directions. In testimony whereof we have atlixedonr signatures.
